Decentralized network 42

Decentralized network 42

Decentralized network 42 (also known as dn42) is a decentralized peer-to-peer network built using VPNs and software BGP routers.

While other Darknets try to establish anonymity for their participants, that is not what dn42 is aiming for. It is a network to explore routing technologies used in the Internet and tries to establish direct non-NATed connections between the members.

The network is not fully meshed. dn42 hardly uses physical links between the single networks but virtual ones. These virtual links use the Internet as transport but are logically independent from it, you can treat a virtual link more or less like a fiber or copper line.[1] Everybody has a VPN connection to one or more participants. The connections are bound to a local DynDNS/DNS address. If you decide to use GRE or SIT the diactc (Diac24 Tunnel Controller) updates the public IP address of the connection endpoint on IP changes. OpenVPN is capable of doing this without external help. In the VPN connection BGP is used for inter AS routing and by default OSPF for intra AS routing, but participants may use another protocol for internal routing.

Network address space consist of private subnets, 172.22.0.0/15 is the main subnet, the AS-Numbers are in the private space from 64601 to 64855.

Hardware used on dn42 consists of routers, which aren't always a cheap solution. There are mainly four implementations for BGP on default hardware. The most common in dn42 is Quagga, a fork of the no longer maintained GNU Zebra, which runs on most Unices from Linux over *BSD to OpenSolaris. Also used in dn42 is OpenBGPD which runs on OpenBSD. There are also the "enterprise class" XORP and the simplicistic BIRD, however those are not very common in dn42. There were also some machines running JunOS, the Juniper Operating system, which is used with professional routing hardware.[1]
